Tottenham defender Pascal Chimbonda has warned Arsenal he is determined to give them another dose of League Cup despair.
Chimbonda admitted morale was low in the Spurs changing room after his side threw away a two-goal lead in the first leg of their League Cup semi-final clash against Arsenal on Wednesday.
Arsene Wenger's side have the advantage after the 2-2 draw at Spurs because they will play next week's second leg at home and can go through to the final without winning.
A 0-0 or 1-1 draw after extra-time would be enough for Arsenal to set up a showdown with Chelsea at Cardiff's Millennium Stadium next month.
But French right-back Chimbonda knows exactly what it takes to knock Arsenal out of the competition against the odds after playing in Wigan's semi-final victory against the Gunners last season.
Wigan were 2-1 down on aggregate with just a minute to play in the second leg when Jason Roberts scored to stun Arsenal and send Paul Jewell's team into the final.
Chimbonda believes Spurs can emulate that achievement and he said: "I know we can win there because I went to Arsenal with Wigan at the same stage last season and we got the result we needed to go through.
"Wigan got the goal we needed at Highbury so anything is possible for us at the Emirates. If we play the same as we did in the first half of this match, then we can definitely score there too.
"I know what it takes to beat Arsenal to get to the final and Tottenham are good enough to do it.
"I don't know if Arsenal are a stronger team than last year, but it would be really special to be the first team to win at the Emirates."
Spurs were thrashed 3-0 at Arsenal in the Premiership last month and have failed to beat their bitter north London rivals in 16 attempts.
They were in the perfect position to end that dismal run as they stormed into a 2-0 lead against an inexperienced Arsenal side.
But Wenger's young guns battled back as Julio Baptista scored twice in the second half to leave Chimbonda stunned.
"We are very disappointed to have drawn the game especially as we were winning 2-0 at half-time," he said.
"It has left a bad feeling in the dressing room but Arsenal played well in the second half. We were defending for the whole 45 minutes and it was always going to be difficult to hang on to our lead.
"They are back in the tie, but there is the second leg next week and we still have a good chance to get to the final."
